cNIS Update Anand Patil, DANTE NML-WG, Open Grid Forum 22, Cambridge (MA), 26 February 2008
Contents • Introduction • Schema • Current Status • Future Plans • Summary
Introduction • common Network Information System (cNIS) • Unified repository of relevant network information • To avoid effort duplication, replication of data and inconsistency • Northbound interfaces (use NML instead) • Information about a single domain only • One self-managed instance of cNIS per domain • cNIS v1 deployed Sep 1 2007 • Automatic IP network discovery
Schema • cNIS schema is a RDBMS schema not XML • Flexible design, with a technology-agnostic core such that support for new protocols can be added easily • Time information kept, so that past and future topologies can be accessed • Schema Task Force established • Reviewing IP, Ethernet and SDH schema • Work on OTN, Fibre schema • UML data model in version 0.17 – work in progress
Current Status • Four Bug fixes and feature enhancement releases since v1 • perfSONAR NMWG Topology interface implemented • Tested with DFNs CNM tool • perfSONAR echo request/response interface implemented • http://perfsonar.acad.bg/status/smokeping?target=NMDM.cNIS.GEANT2 • A plugin Network Discovery Framework • Hungarnet working on Ethernet discovery (Net Spotter) • Tested on Renater testbed as well as GÉANT2, GARR and LRZ networks • Trials with other perfSONAR pilot NRENs delayed
Future Plans • cNIS v1.1 to be released in March 2008 • Further refine schema • Integrate with eduGAIN (GIdP), Lookup service • Automated discovery for Ethernet, SDH and OTH layer • Working with Hungarnet (NetSpotter) • Support for initial deployments • Transition to Service • Provide input to, and in future adopt, OGF NML-WG
Summary • cNIS a unified repository of network information • RDBMS schema modelled in UML • Task force working on schema refinement • cNIS v1 released Sep 2007, v1.1 coming soon • Plans to automate lower layer discovery • Transition to service • Contribute to NML-WG and adopt it as standard interface
